Teeb muaj photons - "particles" nrog tsis muaj pawg uas taug kev ntawm qhov ceev ntawm teeb . Lawv muaj lub zog, thiab ib qho kev ntsuas ntawm lub zog no yog "wavelength" ntawm lub teeb . (Hauv qee qhov xwm txheej, teeb muaj yoj khoom - cuam tshuam thiab cuam tshuam kev cuam tshuam - tab sis cov no tsis tshua muaj qhov tseem ceeb hauv computer graphics.)

Ntxiv mus, 5 yam khoom ntawm lub teeb yog dab tsi?

Qhov tseem ceeb khoom ntawm pom teeb yog kev siv zog, kev nthuav tawm kev taw qhia, zaus lossis wavelength spectrum, thiab polarization, thaum nws ceev hauv lub tshuab nqus tsev, 299, 792, 458 meters ib ob, yog ib qho tseem ceeb ntawm qhov xwm txheej.

Ib yam li ntawd, 7 lub zog ntawm lub teeb yog dab tsi? Lub yoj qauv ntawm teeb yog illustrated los ntawm khoom ntawm kev xav, refraction, diffraction, cuam tshuam, thiab polarization.

Kuj paub, plaub yam ntawm lub teeb yog dab tsi?

To taub cov no plaub yam ntxwv ntawm lub teeb - kom muaj nuj nqis, zoo, xim kub, thiab kev taw qhia - yuav tsis ua rau koj tus kws yees duab zoo dua. Cov ntaub ntawv tseem ceeb, paub meej, tab sis nws tsis muaj txiaj ntsig tshwj tsis yog tias koj tab tom npaj coj los ntawm theoretical mus rau lub tswv yim. Teeb yog txhua yam hauv kev yees duab.

Dab tsi yog 3 yam khoom ntawm lub teeb?

Peb thawj cov khoom ntawm lub teeb yog ceev, kev xav, thiab xim. Qhov ceev ntawm teeb yog 300, 000 Kilometers ib ob, uas yog lub siab ceev txwv ntawm txhua yam hauv lub ntiaj teb. Cov teeb hais, los yog photons, xav txog lwm yam hais los yog pawg thiab txuas ntxiv mus rau tib lub ceev.
